Johann Siegfried Hufnagel (17 October 1724, Falkenwalde, Prenzlau district, Brandenburg – 23 February 1795, Langenfeld, Sternberg district) was a German parson and entomologist (lepidopterist). Life Until the late 20th century nothing was known about Hufnagel's life. Even his first names remained unknown. In 1987 Gerstberger and Stiesy succeeded in identifying him with the help of Fischer's work (1941) and uncovered some basic biographical information. Hufnagel came from a family of Protestant clergymen, his father and grandfather before him having been parsons. Johann Siegfried probably attended one of the universities in northern or eastern Germany (but not in Berlin as Berlin had no university at the time). From 1759 to 1767 the Berlin address book mentions one "Hufnagel" or "Huffnagel" who was praeceptor (teacher) at the Protestant-Lutheran church near the Grosses Friedrichs-Hospital und Waisenhaus (hospital and orphanage) and lived in the orphanage. As this is consistent both with the career progression of young theologians at the time who often worked as teachers before their first appointment and with Fischer's records it seems safe to assume that this was indeed the lepidopterist Johann Siegfried Hufnagel. He had his first position in 1767 in Petersberg (Oststernberg district; today Jemiołów, Swiebodzin district, Poland). From 1775 until his death in 1795 he was the parson of Langenfeld (Oststernberg district, today Długoszyn, Sulecin district, Poland). Achievement and Impact Between 1765 and 1767 Hufnagel published thirteen papers on Lepidoptera (moths and butterflies), ten of them during 1766, and all in the journal "Berlinisches Magazin, oder gesammlete [sic] Schriften und Nachrichten für die Liebhaber der Arzneywissenschaft, Naturgeschichte und der angenehmen Wissenschaften überhaupt", one of the learned journals covering a wide range of aspects in the fields of natural history and medicine which had been founded during the 18th century. One of his papers was devoted to agricultural pests, four contained descriptions of single species treated in some detail and accompanied by illustrations. The other eight papers formed a treatment in tabular form of the larger Lepidoptera (mainly the so-called Macrolepidoptera) of the Berlin area which were represented in Hufnagel's collection. Later authors often referred to this series of papers as "Die Tabellen" (the tables). Due to this form of presentation the descriptions of new species are very brief. A further impediment is Hufnagel's lack of a terminology for the wing pattern elements of Lepidoptera which makes his descriptions difficult to interpret even for native speakers of German. For
